New stars like our Sun

NASA researchers estimate that there are billions of yellow, dwarf-like stars in the Milky Way in the Milky Way, and that more than half of them could host at least one exoplanet in their habitable zones.

It should be noted that this estimate is not a guarantee that any of these exoplanets are or have ever been habitable. But the study by NASA scientists provides the most accurate balance of the number of planets in the galaxy that, at least in theory, could meet the requirements for hosting life.

Experts explain that there are many factors to consider when a study tries to determine the "habitable zone" of a star. The most important of these are: the distance between the star and the surrounding planets and the temperatures felt at the surface of the planets.

According to Futurism, the new study did not consider any of them, but only calculated how many Sun-like stars an exoplanet could have, in what could be a reasonable approximation of a habitable zone. This approximation of the limits of the habitable area was obtained by compiling the data obtained from previous studies.

Based on a series of data and assumptions about the stars and solar systems in the Milky Way, scientists have concluded that, on average, there are between 0.37 to 0.60 exoplanets in a habitable zone and 0.58 up to 0.88 exoplanets in a wider and harder area, but with habitable potential.

New informations about the Dead Sea Scrolls

The famous Dead Sea Scrolls continue to generate riddles, decades after their discovery. A recent study concluded that at least one different technique was used to obtain one of them than the rest, an unknown technique, unheard of to this day. The parchment that attracted the attention of researchers, one of the most important in the collection, is one with an age of almost 2.000 years, which has been remarkably well preserved, despite the conditions in which it was kept and despite its size. of the largest. Found by the Bedouins in 1956, north of the Dead Sea, it was sold to an antique dealer. He did not keep it in the best conditions, but still wrapped it in cellophane and stored it in a shoe box, hidden under the floor, according to Science Alert. The "Temple Parchment", as he is known, has survived, but is currently the thinnest of the parchments (a collection of about 900 pieces). It is only one tenth of a millimeter thick. However, it was preserved, and the material ...

Final resting place of Alexander the Great

One of the versions regarding the location of the tomb of Alexander the Great mentions that the body of the great conqueror was deposited in a golden coffin, which was sent to Memphis, Egypt, and from there to Alexandria (city founded by Alexandru), where he lost track. It was thought for a time that the sarcophagus of Alexander the Great was found in Sidon (Lebanon), because the warrior with a lion's helmet carved on one side looked very much like Alexander the Great. It was later discovered that this was, in fact, the coffin of the king of Sidon. However, the search did not stop there. In 2014, the tomb of a military commander allegedly contemporary with Alexander the Great was discovered in central Macedonia. Although some historians are convinced that these are the remains of Alexander, his place of rest is still sought.

Tomb of the Red Queen, Mexico

In 1994, archaeologists discovered a mortuary in Palenque (a Mayan city). They found here a coffin with the remains of a woman, covered in red dust. Several collections of pearls were also found inside, and a diadem had been placed around the skull. Pieces of what had once been a funeral mask were also found at the scene. According to researchers, the Red Queen was around 60 at the time of her death. This was an interesting finding, as power was usually inherited only by men. As far as was known until the date of this discovery, women were not honored to such an extent that they were buried with treasures such as those found in the Red Queen's coffin. Who was this woman and how much power was concentrated in her hands? It is unknown at this time ...
